Now that former Steelers K Jeff Reed has taken some time off to collect himself, he’ll try to rejuvenate his career across the country in San Francisco.

Reed signed with the 49ers today, CSNbayarea.com confirmed, a few days after San Francisco cut K Shane Andrus – who made 2 of 4 field goal attempts in two games with the team.

The signing of Reed - who made 15 of 22 field goals this year but missed three of his last seven in Pittsburgh- means regular 49ers K Joe Nedney, who’s been out the past two games with a sprained knee, isn’t ready to return to action. It also means Reed’s tenure in San Francisco might be rather short.

Denver LB D.J. Williams, who’s not had such a great past few weeks, is questionable to play with a concussion. Following his arrest on a DUI charge two weeks ago, he was knocked out of Monday’s game after a blow to the head. But he returned to practice two days later, so it looks like he’ll probably play. LB Robert Ayers is probable to play.

Three of the four St. Louis players on the injury list are probable. That leaves only WR Danario Alexander as questionable. Apparently, he had a great practice Wednesday, and it looks like he’s ready to make his first game appearance since Oct. 24. Chargers at Colts

The biggest star for San Diego, TE Antonio Gates, is questionable with plantar fasciitis, but it seems highly unlikely he’ll play, because he’s still in a significant amount of pain. WR Malcom Floyd is questionable with a hamstring problem, but Chargers QB Philip Rivers will be happy to welcome back WR Vincent Jackson to the team. Also, WR Legedu Naanee, who hasn’t played since Oct. 3, is probable.

K Joe Nedney is doubtful with a knee injury, and he’ll likely miss his second-straight game. San Francisco signed Shane Andrus to replace him Nov. 17, but since the 49ers were shut out last week, he wasn’t needed. It’s likely that won’t happen two games in a row.

For Arizona, DE Calais Campbell is questionable with a bad ankle, and he’ll be a gametime decision for Monday Night Football. Though LB Clark Haggans hasn’t played since Week 7 and is questionable, it sounds like he’ll be ready to play. As will RB LaRod Stephens-Howling, who also is questionable and very well could play.
